On the eve of the Massachusetts Primary, Kraft avoided bringing up Trump's politics, but he did extol the bombastic billionaire's character.

“After my wife passed in 2011, he was one of the few people who went out of their way and went above and beyond to assist me through the most difficult time in my life,” Kraft said. “I will always be grateful to him for his thoughtfulness and his continued friendship.”

Brady, much like Kraft, has lauded Trump as a person. Brady said in December Trump was one of the first celebrities who befriended him after he won his first Super Bowl 15 years ago.

Though Kraft's comments may appear to be a tacit endorsement of Trump, it's important to keep in mind his recent political donations skew Democratic. The Big Lead calculates Kraft donated $240,300 to politicians and fundraising pacts from 2008-2014, with 63.8 percent of those contributions going to Democrats.

More anything, it appears as if Kraft’s goal with his political contributions is to wield influence rather than promote a specific set of policies. He gave $25,000 to joint fundraising pacts supporting Barack Obama and John McCain in 2008, for example. (Kraft also pledged $57,900 to the Obama Victory Fund in 2012.)
